i A'Ihis linventionrelates to; anfapparatus or device. which'fisespecially, bui-,.fnot necessarily,pdesigned` 'for-'farm usage,andconstructe'd to providea Convenient andfreliable lliconveyance fortransporting land handlingv heavy containers such as oil and gasolineand fuel drums. 1

Briefly stated, the invention'has toy do with a wheelsupported frameconstituting 10 a carriagev for a super structure on which a platform ismountedfor vertical adjustment, y

said platform being provided with supporting blocks especiallydesignedto 'accommo-` 1 date two or more horizontally disposedliq- 15uid containing'drums or barrels and said platformfhaving means whereby4Vthe eleva-f tion thereof can be varied and held to maintain theV drumsatan appropriate elevation f for convenient dispensing purposes;V

It frequently happens `that the route of.,

' a tractor or farm machine may Abe. overa comparatively great areawhileV performing the days work and it is obviously convenient toprovide a trailer to be attached thereto whereby said trailerisconstructed to support barrels or drums for containing` reserve oil-andgasoline for lubricating and fuel purposes.

Itis therefore an object of the invention to 0 provide a simple andeconomical wheel-supported conveyance which will accomplish this resultin a satisfactory and dependable manner.

The particular details and mechanical coordination thereof in thedevelopment of this improved addition to the art and trade will becomemore readily apparent from the following description and drawings.

In the drawings: v K

Figure 2 is a top plan view thereof. Figure '3 is a side elevation ofthe upper portion of the structure. i

Figure 4 is a horizontal sectional view. In the drawings, in Figure l,`the numeral 5 designates a wheel supported carriage 5d which includes ahorizontal frame 6 of appropriate construction supported on transport-Rising@Y saddle.

from vthfefour corners of the frame 6 arey standards or'posts l() joined,together by suitable. connecting members, 11. yEach post formed with.a1 substantially Lfsh'aped n groove or .gulid-eway12. The;` numeral 13y Adesignates diagonal :corner braces .between the frame 6 andthepostslO. The numerals .1111 represent vretainingpins carriedby-suspension *chains*v 1,5, saidV pins being adapted ."to beinsertedinto keeperholesl to sus end .the hoisting platform T17 in `Yanelevate poi" sition. Y i' i f This platform is inthe form of Kan open--woprkl frame Vandjincludes spacedr parallel .angle irons 18,.,eachhaving aisubstantially L,- v i' shaped 'guide.lugA 19 at opposite ends.and said guide-.lu'gs are fitted 5in' the correspondingly shaped guidegrooves 12 lof the post. Thisv arrangementpermi-ts. .free sliding.l ofthe frameor platform V1'?l and-.avoidsjdisplace- ,751.

` of the head of the drum as represented for example infFigurel; Thesehook bolts yproidefclamps for .holdingthe` drum-.in lthe Y. expansible'and contractible raising and lowering mechanism is arranged betweenI thefra-mes, i6., Y 17 to permit'. the raising; for

lowering of the fr ame'or platform 117. y

-Thisv'mechanism comprises apa-ir of spaced parallel horizontallydisposed bars' 24fand 25`which co-operate with the right a-nd .left hand.screw-threads l: 26 and 2 27 respectively ofaffeed Lscrew28'. .Y Morespecifically, ythe feed screw is 'threaded'. through I the Ain'terfVmediate 'portions of the cross bars 24; and 25l VAr pair of lazy tongdevices are also provided and each device is represented by the numeral30. rlfhis device comprises a pair of lower links 3l pivotally connectedas at 32 to the opposite ends of the adjustable bar members 24- and 25.The lower ends of these links however are pivotally anchored as at 33 onthe frame 6.

(lo-operating with the links 3l are additional companion links 34;disposed in intersecting relationship and pivotally connected at theirlower ends with the bars 2li and 25 and pivotally connected at theirupper ends as at with the elevating or hoisting platform 17. Assumingthen that the barrels or drums 2l are seated in the saddles 20 and arefastened therein by the hoolbolts 22, it is obvious that the structureis in readiness to transport the drums to the desired place and topermit the drums to be raised or lowered to a desiredr elevation fordispensing purposes.

Through the Vmedium of the feed screw 28 and its crank 29 and theco-operating actuating bars 24 and 25, and right and left hand threads,it is possible to expand or contract the lazy tong devices 30 onopposite sides of the apparatus to raise or lower the platform 17.Consequently the carriage can be hauled from place to place by separatedraft means or can be hooked to a tractor and carried along with thetractor. Then when it is desired to raise the drum this can beexpeditiously accomplished by the mechanism just described. The resultis a saving in time and labor and convenience in the handling of heavyfluid drums of this character.

The gist `of the invention is in the provision of a properly balancedcarriage having a suitable center of gravity and a superstructuremounted thereon and including posts to accomodate the platform 17 andraising and lowering meansv therefor.

While the preferred embodiment of the invention has been shown anddescribed, it is to be understood that minor changes in shape, size,materials and rearrangement of parts coming within the field ofinvention claimed may be resorted to in actual practice, if desired.

I claim: f

The herein described portable apparatus for the purpose described,consisting lessen- .1 tially of a frame having upstanding corner postsand guideways in said posts, the 4upper portions of the posts beingapertured, ground wheels connected with and supporting said frame, avertically movable platform disposed between said posts and interlockedtherewith, pins flexibly connected with the upper portions of the postsand adapted to be arranged in the apertures thereof to positivelysupport the platform in an elevated position, lazy-tongs arranged atopposite sides of the wheel-supported frame and including transversebars with appropriately threaded central horizontally disposed andaligned apertures therein and also including lower side links crossedand connected at their lower ends to opposite end portions of the frameand at their upper ends to said transverse bar, and upper crossed linksarranged at opposite sides of the apparatus and connected at their lowerends to said transverse bars and'at their upper ends to opposite endportions of said vertically movable platform, and a longitudinal centralscrew mounted in the frame and having oppositely threaded portionsengaging in the threaded apertures of the transverse bars and alsohaving at one end a handle.

In testimony whereof I afiix my signature.

GLENN ANDERSON.
